Key Functions and Features for advanced video surveillance system

This document describes the histories, core technologies, and customers' benefits of our security business activities relating to the "visual security products" offered by Panasonic, based on the technical and product aspects. Together with supporting the security and safety of customers' properties, the aim of the document is: to provide products that care about operators and installers involved with security that incorporate the technologies to save costs not only for introduction but also operation and that are eco-friendly as well as to explain their characteristics.

Nature has given severe challenges to video surveillance. While indoor lighting may have a not-so-wide dynamic range, natural light such as direct sunlight causes difficult lighting conditions. Adverse weather conditions such as snow and rain may also cause poor visibility. In low visibility, it is difficult for security personnel to identify suspicious objects and movements, or to monitor road traffic conditions and rail infrastructure. But the great need exists for reliable surveillance and remote monitoring in these challenging conditions.

With the increasing concern over better protection of people and assets, security departments are required a higher level of security than before: proactive prevention, earlier detection, a better situational awareness, a quicker identification, a prompter action and more. It is essential to conduct surveillance in a well-planned manner, give security staff good training, and ensure good communication between all related parties. Video surveillance has also become essential. Now many organizations are continually reevaluating and enhancing their video surveillance system to provide optimal daily security and operational efficiency.

With the growing concern over physical security, surveillance cameras have been installed outdoors more and more in every industry sector and public space from towns, airports and railroad stations to offices, retailers, healthcare providers and more. Installing cameras under the open sky with expensive outdoor housings became required. Today outdoor-ready cameras offer high-waterproof performance. External housings are no longer required but other points need to be considered when installing cameras outdoors. Panasonic has shipped the largest number of outdoor vandal resistant cameras in the security camera industry. This paper describes the considerations and latest technologies for outdoor surveillance cameras.

Surveillance cameras are seeing almost daily advancements in the areas of lenses, imagingsensors, and image signal processing. This is done to allow subjects monitored, such as peopleand cars, to be more clearly recorded. Resolution in particular has gone from analog resolution(720 x 480) of a decade ago to HD (1280 x 720), FHD (1920 x 1080), and 4K (3840 x 2160) in thepast few years, and even higher definition will likely be achieved in the future.With the advance to high definition, data volumes for video are increasing to levelsincomparable with those of the analog age. Due to that, costs for networks to deliver that videodata and recording media to store it are becoming major issues.Meanwhile, not all of the video recorded is of use by customers, and in most cases it isdisposed of without being checked even once. For that reason, technology to allow delivery andsaving/storing of just the video really needed (video that includes the subject monitored) andthereby reduce costs is demanded.

Cyber attacks on IoT devices are on the rise in recent years, with video surveillance systems connected to the Internet also being the target of cyber attack. Resistance to cyber attack is thus becoming an important factor to look at when selecting the appropriate video surveillance system. Some models of Panasonic’s i-PRO series cameras ship with digital certificates preinstalled, and they can they can encrypt communications, detect alteration, and prevent spoofing right after being set up. By equipping with data encryption functions, countermeasures against data leakage can be performed end-to-end. This white paper explains i-PRO series security functions of communications encryption and falsification detection using digital certificates as well as data ciphers.
